Specification of Letters Batent.

Patented June 19, 1906.

Application filed August 12, 1904. Siial No. 220,447.

To all whom it may concern; Be it known that LJAMES E. OoLLINs, of Danvers, county of Essex, State of Massachusetts, have inventedan Improvement in Heel-Nailing Machines, of which the following description, in connection with the accompanylng drawings, is a specification, like I characters on the drawings representing like parts.

In the manufacture of shoes or slippers having wooden heels, or what are generally known as French heels, which are usually made of wood, it has been customary to attach the heels to the heel-seat of the shoe by driving the heel-nails by hand from the inner side of the shoe into the heel, it being impossible to secure them by means of an ordinary heel-nailing machine, which drives all the nails simultaneously, as the heel would be broken or split.

My invention has for its object to provide 7, an improved means for securing a wooden heel to the heel-seat of a shoefto reduce the cost of performing this part of the process by facilitating its performance, and to enable the heels to be secured with greater uniformity or accuracy.

In carrying out my invention I employ suitable means for sustaining a shoe and heel in such relation that the heel will be in alinement with the heel-seat of the shoe. Anail- I I is provided and is arranged to enter the shoe.

The construction is such that relative movea nail-delivering nozzle is mounted in stationary position and the shoe and heel sustaining means is freely movable in a directiontransverse to the path of the nails both I Fig. 3 is aplan view thereof. Fig. 4 is a de-.

laterally and longitudinally of the heel. The shoe-sustaining means is manually controlled and manipulated to advance the work to the extent desired after each insertion of a nail.

Other features of the invention will be hereinafter described.

In the drawings, Figure 1 illustrates in side elevation a machine embodying ,my invention. Fig. 2 is a longitudinal-central sectional view of theshoe and heel support, and

tail end view of one of the heel-clamps. Fig. 5 is a section on the line (1 d of Fig. 2. Figs. 6 and 7 are enlarged sectional plan views on. the line a a of Fig. 1. Figs. 8 and 9 are sectional views on the line b b of Fig. 1. Fig. 10 is an elevation of the end of the tack-driver nozzle, and Fig. 11 is a. section on the line 0 c of Fig. 10.

In carrying out my invention I may employ any well-known form of machine which is adapted to force nails from the throat of a nozzle by means of a driver into the work, which is held against the end of the nozzle. As such devices are common in the art a special description thereof is deemed unnecessary. Such a machine is indicated by the numeral 1 in Fig. 1 and is provided with a nail-ej ecting nozzle 2, which for my purposes I make somewhat longer than is necessary for simply driving nails into the sole or heel of a shoe from the outside. Said nozzle is provided with the usual driver 2, which is adapted to be moved to the face of the nozzle when each nail is driven. The nail-drive ing mechanism is controlled by an suitable means, as the footlever 3. The ower end of the nozzle. 2 is provided with a semicircular guard 4, the face or under side of which is upwardly curved from the end of the throat for the purpose hereinafter described.

A support or holder 5 is rigidly secured to the upper end of a rigid rod 6, the latter having aball-and-socket connection with a weighted foot-lever 7, the weight on said leverbeing arranged to lift said rod andfparts supported thereby when the pressure on the treadle of lever 7 is removed. A pair ,of heelclamping levers 8 are pivotally mounted at 8 on the support 5, said levers having jaws 9, the faces of which are adapted to engage the sides of a wooden heel, so that when said jaws are moved together a heel may be firmly clamped between them with its bottom or top lift resting on the top of said support 5. A cam 10 is mounted between the rear ends of said levers, and an arm 11 is-connected thereto, so that said jaws may be readil locked together. A vertical arm 12 is mounted on each lever 8, and each arm has a horizontal spring-finger 13 secured thereto, said fingers extending forwardly divergently directly above and equidistant from the faces of jaws 9. Said fingers are shaped-to correment, means being provided for moving said clamps toward each other simultaneously, consisting of an oppositely-threaded bolt 15,

which is ournaled in the under side of said, support and is provided with a handle 16,

with which it may be readily rotated.

A bracket 17 is secured to the frame near the support and is provided with an enlarged. A

aperture 17, through which rod 6 passes. pair of clips 18, having corresponding semicircular recesses in their adjacent edges, are adapted to be secured to the upper side of said bracket to constitute a bearing for red 6.

The operation of my device is as followsc The support 5 is first drawn down by depressing the treadle of lever 7, and then the jaws 9 are opened. A heel is then placed between the jaws and a shoe which is to be heeled is placed thereon with its heel end between the spring-fingers 13 and its heel-seat in position on the heel. The fore part of the shoe is also preferably secured in place by the clamps 14.

The weighted lever 7 is then permitted to lift the support 5, so that the face of the nailing-nozzle 2 engages the inner side of the shoe directly above the heel-seat. If the heel to be secured is an ordinary French heel or heel in which the bottom side is much smaller than the side which comes next the heel-seat, then it will not be desirable to have the nails driven into the heel at points which are not directly above its bottom side. In such instance, therefore, I secure the clips 18 to the bracket 17, so that the supporting-rod 6 is located in the semicircular recesses thereof and is rotatably mounted therein, the nail passage or throat of the nozzle being eccentric to the axis of said rod. The weight of the lever 7 is SUHlClGIlt to press the inner side of the shoe against the nozzle 2 of the nailingmachine with such force that the nails will be driven through the sole or inner sole of the shoe into the heel. After the nailing-machine drives in each nail the shoe is turned or rotated a short distance by the operator, so that a circular row of nails will be driven into the heel when the shoe has been given a single revolution, as indicated in Fig. 9. In case a wooden heel of the shape commonly employed on mens shoes is to be secured and in which case the nails may be driven close to the edge of the heel the clips 18 are removed, so that the bar 6 may be swung to a considerable extent within the aperture 17 of the bracket 17 Assuming that the parts are moved to the positions illustrated in Figs. 6 and 8, so that the edge of the guard 4 at the end of the nozzle 2 bears against the inner side of the upper, (see Fig. 8,) the shoe will be drawn forward, then moved sidewise, then backwardly, and then sidewise back to the initial position, so that a series of nails will be driven in the line represented by the arrows in Fig. 8. The guard 4 will prevent the nails from being driven within a certain distance from the upper and permits the nails to be driven in even with the surface of the inner sole. The closeness with which the nails are driven together will be controlled by the operator. In this manner the heel will be rigidly secured to the shoe in. much less time than it is possible to perform the same operation by hand, and moreover the heels will be secured with more uniform accuracy than they are likely to be when secured by hand.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:
